You must not exceed the maximum weight limit for the Citi Bike bicycle (260 pounds) or the cargo carrier (17 pounds).

The program, however, has no way to enforce the weight limit, and Department of Transportation Policy Director Jon Orcutt told the New York Post the City does not plan to try: “I think people will be self-selecting, practical and safe.”

Orcutt also said the limit was included for legal reasons.

Citi Bike is scheduled to open this month, though a specific date has not been announced.
